Summary The purpose of this study is to fabricate DSSC which performs well from natural pigments by giving exposure to microwave irradiation in materials to increase pigment uptake. In this research, the microwave irradiation was applied in coating banana flower extract (Musa acuminata bract) on the electrode, to increase light absorption of anthocyanin pigment. It is expected that the device can absorb more solar energy. The banana flower extract was characterized using Ocean Optic Vis‐Nir USB 4000 to observe the optical properties. The irradiation treatment was carried out using Electrolux Microwave (EMM 2308X) at power 150 W. The DSSC samples were characterized using I‐V meter Nacrieble 101. The maximum absorbance of 1.55 a.u. is found for the mass fraction of 0.45. The microwave irradiated device has an efficiency of about 3.69×10−6%, whereas which is no microwave irradiation has a maximum efficiency of about 0.57%. It shows that microwave irradiation can improve DSSC performance. The banana flower extract is available as an alternative organic photosensitizer in the fabrication of DSSC.

The purpose of this research is to fabricate banana flower extracts-based dye-sensitized solar cell (DSSC) using spin coating method. DSSC is made of photoactive material of banana extract by spincoating method and thermal evaporation, using indium tin oxide (ITO) substrate. Spincoater speed, coating duration and heating temperature are fixed as controlled variables, anthocyanin pH is fixed as independent variable, while optical and electrical properties of solar cell device are fixed as dependent variables. The anthocyanin content decreased as well as the pH increased and the voltage knee also increased. The pH enhance has caused the current generation of device decreased.

Photoresist is an essential chemical used in patterning the microelectronic devices. To ensure the sustainability of the supply of raw materials of microelectronics industry such as photoresist need to look for alternative materials that are more eco-friendly. This study used natural ingredients of Hibiscus tiliaceus L. flowers extract. The manufacture of photoresists carried in four stages, the manufacture of Hibiscus tiliaceus L. flowers extract, the manufacture of thin film Hibiscus tiliaceus L. flowers extract, the manufacture of resist and the manufacture of thin film photoresist. The manufacture of Hibiscus tiliaceus L. flowers extract is done with mass fraction variations using distillation methods. The optical properties of Hibiscus tiliaceus L. flowers extract was characterized using ocean optic Vis-NIR USB 4000. The functional group was characterized using the Perkin Elmer Frontier FT-IR, while the surface structure was characterized using the Digital CCD Microscope MS-804 Scopeman and the electrical properties were characterized using the Elkahfi 100 I-V Meter. The density of the resist is characterized by the mass per volume method. Thin film of photoresist is grown through the spin coating method with a voltage of 10 V for 60 s and heating to a temperature of 200°C for characterization of surface structures and optical properties. Photoresist is tested for sensitivity by giving exposure to UV and X-ray radiation sources to photoresist material. The resulting photoresist has a value of absorbance that is located in the wavelength range of 350 to 1050 nm with a maximum absorbance value of 0.07 to 0.3 at the wavelength of the g-line, h-line and i-line.
